[refurb] Add a note about float literal handling (FURB157)#18615
Merged
Conversation
Summary
--
Updates the rule docs to explicitly state how cases like `Decimal("0.1")` are
handled (not affected) because the discussion of "float casts" referring to
values like `nan` and `inf` are otherwise a bit confusing.
These changes are based on suggestions from @AlexWaygood on Notion, with a
slight adjustment to use 0.1 instead of 0.5 since it causes a more immediate
issue in the REPL:
```pycon
>>> from decimal import Decimal
>>> Decimal(0.5) == Decimal("0.5")
True
>>> Decimal(0.1) == Decimal("0.1")
False
```
